Not a Devo fan, are you?

Actually, you aren't. You are, however, free to pick one of many offers, and one of them may suit you better than the others. Perhaps you can negotiate better offers, but this doesn't mean that a potential employer may be willing to present a better counter-offer.

They don't have to be willing to present a better counter. If they don't, you just eliminate them from the pool and your decision is that much easier. If you are afraid to do that, then the multiple offers are only illusory anyway, since you would clearly have a preference you should be acting on.

You're somehow assuming that salary is the only relevant parameter in choosing a job, or even that all jobs are equivalent in career growth and creating more job opportunities. Some jobs are dead-ends and career killers, even if they pay more. This sort of stuff needs to be considered.
